Abstract: L'invention concerne un porte-insecte qui sert à maintenir un insecte d'un type particulier, tel qu'une abeille domestique ravitailleuse. Ce porte-insecte comprend un logement doté d'une enceinte qui est conçue pour accueillir l'insecte de type particulier, une entrée que ledit insecte traverse pour pénétrer dans l'enceinte, une ouverture de tête pratiquée sur l'enceinte qui permet le passage de la tête de l'insecte vers l'extérieur de l'enceinte tout en retenant le corps de l'insecte dans le logement, et enfin, un dispositif de retenue qui permet de bloquer ledit insecte dans l'enceinte pour l'empêcher de tourner dans l'enceinte, tout en laissant sa tête dépasser de l'ouverture de tête vers l'extérieur du logement. Pendant l'utilisation, lorsque l'insecte pénètre dans l'enceinte via l'entrée, le dispositif de retenue le bloque dans le porte-insecte en laissant sa tête dépasser de l'ouverture de tête de l'enceinte. L'insecte ainsi immobilisé dans l'enceinte, avec la tête dépassant de ladite ouverture, ne peut plus rentrer sa tête dans l'enceinte, celle-ci devant obligatoirement rester à l'extérieur de l'enceinte. Par conséquent, la tête de l'insecte reste bien visible dans le porte-insecte, ce qui permet de l'examiner et de surveiller par exemple le mouvement du rostre selon une méthode connue. A la fin de l'examen, on peut enlever ou désactiver le dispositif de retenue pour permettre à l'animal de quitter l'enceinte sain et sauf.

Abstract: The present invention provides a method for the detection and sorting of microparticles in a mixture of microparticles. The method of the present invention allows for the detection and sorting of many distinct microparticle classes. Detection and sorting is on the basis of microparticle size, the fluorescence spectrum of any attached reporter molecule, the fluorescence intensity of the reporter molecule, and the number of particles in each classification bin. These microparticle classes have particular applications in many genetic or biochemical multiplexing studies and especially as binding agents for the detection of aneuploidy in an organism or embryo of the organism. In humans, the detection and sorting of at least 24 classes of microparticles would be sufficient for a single tube method for the simultaneous detection of aneuploidy in all chromosomes, wherein each distinct microparticle class comprises a polynucleotide sequence complementary to, and specific for, a polynucleotide sequence that is unique to a particular human chromosome. Furthermore, using currently available technology, the present method has application for the simultaneous detection of aneuploidy in all chromosomes for an organism that has 216 or fewer pairs of chromosomes. Kits for the simultaneous detection of aneuploidy in one or more human chromosomes are also provided.

Abstract: In accordance with one exemplary embodiment, the present invention provides a welding torch that includes features facilitating aligned assembly of various components of the welding torch with respect to one another. For example, the welding torch includes a nipple that carries a pin member extending from both an inner peripheral surface and an outer peripheral of a sleeve of the nipple.  This pin engages with a slot on a coupling member and a slot on a neck assembly, thereby facilitating proper alignment of the neck assembly, coupling member, and nipple with respect to one another. Moreover, the engagement between the pin member and the slots block pivotal displacement of neck assembly, coupling member, and neck assembly with respect to one another. Advantageously, the use of a single pin member for both slots presents a more judicious construction, leading to reduced manufacturing costs, for instance.

Granted: 2014-07-08
Abstract: Polymer composite films were prepared by solvent casting suspensions of quantum dots (QDs) in cellulose triacetate (CTA) solution. The films were robust and possessed the optical properties characteristic of QDs. Transmission electron microscopy (TEM) images of the films revealed that the QDs were well dispersed within the CTA film matrix. The selective alkaline hydrolysis of QD/CTA films in 0.1 N NaOH over 24 hours resulted in the surface conversion of CTA to regenerated cellulose. Optical properties of the films were probed both before and after the hydrolysis reaction using fluorescence spectroscopy, and were found generally unaltered. The cellulose surfaces of the alkaline treated films allow for facile incorporation of the films into paper sheets.
